On one of my builds, I was running a HD3450 and if I'm not mistaken, I got the 1st driver through Windows Update, then installed the driver from the link I just provided, also, I don't remember if I ran it in compatibility mode, I'm pretty sure I didn't, but I do know that I used the AMD driver suite for that card in Windows 8 with no problems.
In "Device Manager" expand "Display Adapters", then right click on the ATI driver, then click on "Update", then choose "Browse my computer for Driver software", direct it to the folder in;
Yours may show something a little different and you may also get a prompt that, "the driver version you wish to install is older than the one currently installed" or something to that affect, so just install anyway.
Thank you for your support. It worked like a charm. But, remember, 12.6 worked for me, tried also with 12.8 but it didn't work. All games starting with Battlefield 3 work fine now thanks to your help.
